  • Patent number: 9035530
    Abstract: An energy converting device having an eccentric rotor includes a fixed portion and an eccentric rotor. This fixed portion has a central axis, an outer frame, and several fixed coil portions. The eccentric rotor has a bearing, a rotatory shaft, an eccentric arm, an eccentric shaft portion, a supporting plate, an inner annular magnetic portion, and an outer annular magnetic portion. The inner magnetic portion and the outer magnetic portion are concentric and aligned with the eccentric shaft portion. The eccentric shaft portion is offset from the rotary shaft. When the rotary shaft of the eccentric rotor rotates, these fixed coil portions cut through the inner magnetic portion and the outer magnetic portion repeatedly, so magnetic flux passing through the coils alternates accordingly to generate electromotive force. Conversely, it can be used as an electric motor. In addition, it can be integrated with a cycloidal speed reducer to form a motor with speed reduction and torque augmentation capability.

  • Patent number: 8960021
    Abstract: A non-contact type torque and angle of rotation sensing device consisting of a magnetic member, sensing members and a computing unit for measuring a torque being applied to rotate a transmission member and the angle of rotation of said transmission member in a first axial direction is disclosed. The magnetic member defines a first center, and is mounted on and rotatable with the transmission member. The magnetic member deflects relative to the transmission member in a nonparallel manner relative to the first axial direction when rotating with the transmission member. Sensing members induce a magnetic field variation to output respective electrical signals that exhibit a phase difference there between. The computing unit receives and calculates the electrical signals of the sensing member to obtain the amplitude and to further translate the amplitude into torque value and angle of rotation.
